From the Superintendent

Fort Sam Houston ISD has earned a rich history and tradition of excellence since its doors opened in 1952.  We are proud of all our students and staff have accomplished in our 60 plus years and we are excited about all the new learning opportunities our future brings.  
Our District staff has the highest expectations for the academic success of its students.  One of our priorities is to provide engaging, challenging, and meaningful work for our learners.  We also recognize that we must actively engage our community and be united around the shared responsibility of ensuring our youth are prepared for the challenges of the future.  Educational research clearly reflects that when parents work in partnership with their children's teachers, both the children and the schools clearly benefit.
